Lesson notes

Learning Objectives

Indicator: 1.4.2.LI.5 - Recall the basic terminologies such as experiment, events, outcome, trial, sample space, etc. as used in the context of probability and give examples.

By the end of the lesson, learners can:

Define, in their own words, the basic probability terminologies: experiment, trial, outcome, event, sample space, and probability.
State the difference between the terminologies (for example, the difference between an outcome and an event, or a trial and an experiment).
Identify and correctly label the experiment, trial, outcome, event, and sample space in a given probability scenario.
List the sample space for simple experiments such as tossing a coin, rolling a dice, or drawing a card from a pack.
Give at least one everyday example, drawn from Ghanaian life, for each probability terminology and explain why it fits the definition.

Content standard: 1.4.2.CS.1 - Demonstrate knowledge of basic principles of permutation and combination and interpret probability in everyday life. 1.4.2.LO.1 Explain combination and permutation, state their difference and solve basic problems related to permutation and combination. 1.4.2.LO.2 Explain the terminologies in probability orally and find the relative frequency in a given experiment.
Indicator: 1.4.2.LI.5 - Recall the basic terminologies such as experiment, events, outcome, trial, sample space, etc. as used in the context of probability and give examples.
Suggested placement: Semester 2, Week 19 (Week 39 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Collaborative Learning, Initiate Talk for Learning and Talk for Learning Approaches, Experiential Learning
Learning Experience: Learners to engage in brainstorming to discuss the various terminologies associated with probability and experiments
Activity: Initiate Talk for Learning, Experiential and Collaborative learning Approaches to support learners to revise their understanding of basic probability terminologies and give example
Learners working in groups debate each other on terminologies such as experiment, probability, events, outcome, trial, sample space, etc. and provide everyday examples.
Example: Undertake the following experiments and discuss and identify the various basic probability terminologies in relation to experiments such as: i) tossing a coin three times ii) rolling a dice iii) drawing a card from a set of playing cards iv) drawing items from objects in a bowl.
Teaching and Learning Resources:
- Ludo dice, coins, playing cards, objects in a sac or bowl.
